摘要
在前人研究的基础上,提出了一种提升永磁同步电机(PMSM)高速带载能力的控制策略。该控制策略能克服电机在最高转速时无法带载的弱点,可靠性高、易于实现。实现该控制策略的算法包含PMSM的弱磁控制和电压空间矢量的过调制控制,使电机能宽范围带载调速。为验证该控制策略,建立了内置式永磁同步电机(IPMSM)的仿真模型,搭建了试验平台,并进行了仿真和试验研究,验证了该控制策略的可行性和有效性。
On the basis of previous research, the control strategy of permanent magnet synchronous motor （PMSM） with high speed of load capacity was promoted, and the control strategy could overcome the weakness that the motor at the highest speed could not be loaded, high reliability and easy to implement. The algorithm of the control strategy includes the weak magnetic control of PMSM and the over modulation control of voltage space vector, so that the motor could be controlled in a wide range of speed. In order to verify the control strategy, the simulation model of interior permanent magnet synchronous motor （IPMSM） was built, the experimental platform was built, the simulation and experiment were carried out, and the feasibility and effectiveness of the control strategy were verified by sinmlation and experiment.
